Application filed March 25, 1903. Serial 110 423355. I

To all whom "it may. concern:

Be it known that I, ETHAN I. Donns, a

citizen of the United States, residing in Central Valley, in the Stateof New York, useful Improvement =county of Orange and have invented anew and in Motor-Car-Truck *Side Frames, of which the following is atruck side framing,

specification.

My invention relates to improvements. in side framing of motor cartrucks such as used in subways where the electric motors are suspendedfrom the truck structure.

The object of my invention is to provide an im roved construction ofmotor car which will be simple and economical to manufacture, and inwhich all the parts of the truck side framing will cooperate to mutuallyreinforce and strengthen each other, and which will be much stronger andmore durable than the constructions heretofore in use.

A further object is to so constructmy reinforcing cast steel member.having the clamps, tension member, compression member and spring seatscast al integral together, that the same may be readily applied withoutmaterial cost or expense as a reinforcement in of such motor car truckswhich have proven too weak to answer re uirements of continued serviceIy invention consists in the means I employ to practically accomplishthis object, as more particularly specified in the claims.

In the accompanying drawing forming a part. of this specification,Figure 1 is a side elevation of a motor car truck side framing embodyingmy invention. Fig. 2 is a'dia-.

the ordinary constructions now in use, and

the

grammatio ;view illustrating the old con-' struction of side framingheretoforecommonly in use, for the purpose ofbetter indicating howily-reinforcing cast steel member me. here plied thereto without materiall tunbmg' the other parts of such true s as are now in use all overthe countryand need tobe reinforced. Fig. 3 is a bottom view of m'reinforcing cast steel mem ber. Fig. 4 i usti'ates a modification inwhich the upper "or compression member of the truck side frame is madeintegral with my reinforcing cast steel member,

In-the'drawing, A represents a portion of a motor car such as s commonlyused In subways and interurban GTV1G6, and B the and interurban service,and.

In the modification illustrated in Fig. 4;, the compression member'D andcasting H are both made in-one integral piece, the construction andoperation beingotherwise the ber to suit those in the, old truck towhich.
